the works pipe which is hand made is $300 but there are regualr stamped pipes and the factory lok one is $110 :clue: anyone know if they are good pipes?
there are also 2 different pipes.. the mid-top sounds the best.. here are reviews from dirt rider magazine..
DYNO PORT TORQUE: Don't let the design fool you! The Dyno Port Torque pipe barks up top. On the stock YZ, the DP pipe felt much like the FMF/SX silencer combination, but with a better midrange hit. On the piston-equipped bike, the DP exhaust produced a hard-hitting powerband similar to the FMF/SX combo, but with a tad more on top. Definitely a solid performer.
DYNO PORT MID-TOP: This was without a doubt the most specialized pipe of the bunch. Low-end power was seriously enhanced on both machines. Midrange was about the same as stock and--as advertised, top end was off the charts. Perhaps on wide open, sandy tracks, the Mid-Top pipe would be favorable, but we have no such tracks in our Southern California testing locale
